Therefore, there should be a relationship between hardness and Young's modulus. We demonstrate this. The calcium content of cancellous bone and adjacent compact bone in several species shows little difference, the cancellous bone having approximately 10% less calcium. The hardness of cancellous bone in Bos is Cited by: 161Publish Year: 1989Author: R. Hodgskinson, J. D. Currey, G. P. Evans
How are Young's modulus and elastic recovery related?
Hard materials are currently characterized by their hardness, H, effective Young's modulus E *=E/(1 2) and elastic recovery W e, where E and are the Young's modulus and the Poisson ratio, respectively.See all results for this questionHow are elastic modulus and hardness of indentations related?In non-metals, a large fraction of the indentation deformation is elastic, so the two properties are not truly independent.See all results for this questionOn the Relation between Indentation Hardness and Young's relationships between hardness young s modulus and polishingAbstract A relation between British Standard and International rubber hardness and Young's modulus is derived from classical elasticity theory, and compared with the empirical relation given in B.S.903:1950. An experimental examination of the load-indentation relationship for a rigid sphere pressed into a flat rubber pad is described ; it indicates that the theoretical relation is more appropriate than the empirical
